Abstract: A method for predicting a construction-related driving-route change of a driving route for a vehicle includes at least a step of reading in and a step of detecting. In the step of reading in, at least one image signal is read in, which represents an image, recorded by the vehicle, of a construction-site parameter in the environment of the driving route. In the step of detecting, the impending driving-route change is detected using the image signal.

Abstract: A method for validating a digital map for a vehicle, including radar-based ascertainment of driving-environment data with the aid of an ascertainment device of the vehicle, comparing the ascertained driving-environment data to corresponding data of the digital map, and Verifying a validity of the digital map for the case when the driving-environment data, ascertained based on radar, coincide to a defined extent with the data of the digital map.

Abstract: A method and an associated system for vehicle localization are described. The system includes a first sensor unit for determining a relative movement of the vehicle in relation to at least one feature in the vehicle surroundings and a second sensor unit for detecting radar data of the vehicle surroundings. The system also includes a memory for storing a digital map, a localization unit, which is configured, for ascertaining a preliminary position indication, to localize the vehicle in the digital map based on the relative movement determined by the first sensor unit, and a position determination unit, which is configured to compare the radar data detected by the second sensor unit with the digital map while taking the preliminary position indication into account, and to determine a position of the vehicle based on the comparison.
